Vehicle Expense Tracker

ASP.NET CoreReactTypeScriptPostgreSQLDockerEntity FrameworkTailwindCSSRechartsFly.io

A full-stack total cost of ownership (TCO) calculator for vehicles with expense tracking, fuel efficiency analytics, and cost trends.

Why this project exists: I built this to explore real-world vehicle ownership costs through data-driven insights and to gain hands-on experience with ASP.NET Core backend development, multi-type data modeling, and full-stack deployment using Docker and cloud hosting.

Focus: Backend API design with ASP.NET Core and Entity Framework · Multi-vehicle type support with smart energy calculations · Data visualization and TCO analytics
